The globular cluster M3 (NGC 5272) in Canes Venatici will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of +28°22', it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 41°S.

From Ashburn (click to change), it will be visible all night. It will become visible at around 20:55 (EST) as the dusk sky fades, 37° above your eastern horizon. It will be lost to dawn twilight at around 05:23, 37° above your western horizon.

At magnitude 6.4, M3 is quite faint, and certainly not visible to the naked eye, but can be viewed through a pair of binoculars or small telescope.

The position of M3 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M3 13h42m10s +28°22' Canes Venatici 6.4 16'12"

The coordinates above are given in J2000.0.

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
